OL BURNER.

Apploation lled July 11, 1922. Seal No. 574,147.

To al! w 710m 'it may conce/m Y lie it. known that l, DE lvrr'r (l. il Hfvrijnr, n citizen oi' the `United States. residing;f at

I l l r n I Lihue. countyoi lxauai, and lerritory of llawali, haue invented certain new and usel'ul lniprownionts in (lil Burners; und l do declare the following to be a Jfull., clear, und

cram description o'fthe invention, such as will enahio others skilled in the art to Awhich it appei'tains to make and use the seme, reference being had to the accompanying drawings. and to the characters of reference marked thereon, which forni a purt of this specil'calion.

This invention relates to oilburners on the type usually employed in connection with boilers for heating writer or generating steam.

-lt is thc object of this invention to produce an oil burner that does not require the oil supply tank to be. placed Vabove the burner, :is is the usual case, but which will lift the oil as high as 2:2 feet, thus permittingr the oil supply or storage to be placed in the basement of permanent plant buildings, or in the iower holds of steaniships. Another object of this invention is to produce a burner that will thoroiighly atomize the fuel so that the combustion will` be complete and instantaneous, und thereby secure a very high thermal eiiiciency and avoid the production of smoke. A further object of this invention is to produce a very simple burner that can be cheaply und conveniently made,l which will not get out of order, and which can also beiernployed as u, burner for blacksmiths" forges and. for similar uses.

' ln order to more clearly describe my involition, shall have reference to the eecoiinpenying drawing, in whichn Fig. 1 shows n longitudinal section of my improved burner;

Fig. 2 shows u modified form of nozzle. adapted more especially for a square fire box; and

Fig. 8 is e in Fig. 1.

The same reference characters will be used to indicate the same parts throughout the several views. A

body member 1. preferably otl circular cross section, is provided with end Walls 2 and 3 and with transverse walls 4 und Walls 2, 3, l and 5 divide the interior oi' the body member l into three compartments plan view of the burner shown or chambers A, B and C, the purpose and functions ot' which will hereinafter appear.v

End wall 2 hns an opening 6 of sulicient size to permit the gland 7 to be inserted therethrough. Within the opening 6 there is a plug 8 provided with an opening 9 which is threaded and adapted to cooperate with the threaded portion of the stem 10. The outer end ot' plug 8 is recessed for the reception ot' packing material 11, which is held in place and compressed by means of the glnnd 12. The stem l has a hollow projecting portion 13 Whose end is enlarged :is indicated at 14 and cooperates with the inclined walls 15 in the wall 4to form avalre, the purpose of which will appear as the description proceeds. Stem 10 is provided with an enlarged cylindrical portion 16 which cooperates with a central o suing in the wall to form a sliding and rotating connection7 which is sealed by means of the pecking 17 held in place by gland 12. The portionot` stem within chamber A is provided with a plurality of holes 18 which communicate with the opening 19 in the tubular member 13.

Steam is admitted into chamber A through the opening in pipe 20, und passes from the chamber through. openings 18 and into the tubular opening 19 in member. 13 .and out through the nozzle 21 into the Venturi tube 22. Pipe 23 extends to the oil supply,

and when valve member 14 is 'withdrawn Irom the cooperating surface 15 so-as to leave a space between the two, the' interaction of the steam und the Venturi tube `Will cause u. partial vacuum to be formed in chamber B, which Will lift the oil from the supply tank into chamber B where .it will become heated before it enters the Venturi tube 22. The steam emerging at high velocity from the nozzle 21, atomizes the oil to some extent and forces it through 'the Venturi tube. at a, high Velocity, in ,the same manner in which Water is raised and forced into a boiler by en injector. End Wall 3 has u central opening 24 in which is threadedly connected a pipe 25 Whose inside diameter is largerthan the outside diameter of the Venturi tube. An annuler space 26 is thereby formed between these two tubes (22 and 25). end of tube 25 is e burner 27,'Which may be spherical in shape and provided With e slot 223 through which the sterilized oil spray Secured to the outer lio folrmly minutely rdouble atmization, the oil is thoroughly broken up and enters the furnace in a anisubdivided condition, 'which permits the combustion to be rapid and complete whereby a very intense heat is generated and all smoke and soot eliminated.

/as steam is usually more readily Pipes and 30 may be provided with suitable valves for the controloi' the steam supply.' These valves have not been4 shown, 'as 4to supply them does not form part ot' this invention.

In the same manner pipe 23 may be provided within the oil supply tank with van ordinary foot valve, which will preventthe pipe from draining when the burner is inoperative.

-Instead of steam, air can also be employed for the operation of the burner, but available than compressed air, I prefer to use the steami vvair under pressure. nected to the oil supply tank. 'mitted through pipes 2O and 30, and hand- Where the burner is to be used in a circular fire, boX or furnace, a tip Ilike that indicated by`numeral 27 in Fig. 1 may be used, and where a rectangular lire box is used, a tip like that shownin Figs. 2 and 3 may preferably be employed?` Theoperation of my device'iskas follows: The burner is attached to the furnace in any approved manner and pipes 20 and 30 are connected `to a source of stean'ror The pipe 23 is con- Stcam is ads Wheel 31e is then rotated so as to open the 'valve between chamber B and the Venturi tube 22. Oil will then be sucked into 'the chamber B and into tube 22, and subjected Ato' the first atomization. It then passes. into tube 25 where the steam from chamber C atomizes the same the second time. The

voil then passes through pipe 25 and through the tip 27 into the furnace, where the combustion takes place.`

Having new described my invention, what I claim as new is: i

1. An oil burner having a central chamber adapted to receive oil, means connecting said chamber to a source ot oil supply, means for producing a partial vacuum in said chamber whereby oil is caused io flow thereinto, a steam chamberai each cud of said central chamber, means i'or conducting steam into said'last named chamber. a tubular valve member extending from one steam chamber through the central chamber. and provided with means cooperating wth au opening in the wall between thil central chamber and the second steam chamlwr, whereby the opening' may be closed or opened,` a Venturi tube secured to said wall, a nozzle secured to said tubular vvalve member and extendinginto one end of said venturi, atube surrounding said Venturi tube concentric therewith and spaced therefrom. whereby an r,annuiarpassage is formed between said'tubes'/sai l/ passage being connected to one'of the steam chambers, and meansr for controlling said tubular valve.

2. A device of the class described, comprising, incombination, a body member hav-` ing a central chamber adapted to receive oil, an end Vchamber on each side o l said central chamberfor the receptioiroi' a iuid under press t re, tatably moui ted in said body 1uembera portion of Said valve member having a slidable and rotatable connection with one wall of the central 4.chamben 'a nozzle 'secured to said valve member and projecting through.

i an opening in the ,opposite wall ot' the eentral chamber, aA Venturi tube secured to said -last named opening and adapted to receive said nozzle, a tubular member secured to ,the end ofthe body member'and surrounding the Venturi tube and concentric therewith, the inner diameter ofthe tubular member being greater than/ theoutside diameter of the Venturi tube whereby an annular space is ormed,"a. burner on the endet' said tubular member, and means for -operating the valve member. l
